#Enhancement of biofilm formation indicated as%. The percent biofilm reduction or enhancement for each isolate was determined after normalization to negative controls, which were not treated with the enzymes; averages are the means ± standard errors (SEs) of the means from four independent experiments. B: burn; Cl: contact lens; E: eye; U: urine; W: wound.
